Wound healing pines question - Field Grown Pine styling part 2

I’ve just caught up on the latest stream and having a hard time visualising a technique Ryan described.

Ryan was discussing a technique of healing the wound left by removed branches and from what I understood, a portion of the core, a stub, is left in place for callus to heal to? Is there a resource I can look up, feel like a picture would save a thousand words?

Thanks in advance

Take a look at this stream where Ryan discusses the technique:

Thank you Roger_Snipes - I was wondering about this too.

Thanks very much! I will have a look now :slight_smile:
